When the movable contactor 7 is connected to and the power is supplied from the regular power source side, the open / close display pointer 90 is maintained in the horizontal state of the side and the "normally on" power is applied to the regular power source. Is displayed. When a power outage accident occurs on the side of the service power supply while the current is being supplied from this power supply, the power failure accident is detected by the detection unit (not shown). Further, the power supply to the normal electromagnetic drive unit 4a is also stopped due to the power failure, the exciting coil 41a of the normal electromagnetic drive unit 4a is demagnetized, and the attraction of the iron core 42a by the exciting coil 41a is also deenergized. The attraction force of the iron core 42a also eliminates the contact pressing force of the movable contact 7 against the stationary fixed contact 5a, and the movable contact 6 is rotated 90 degrees to the neutral position in the shut-off state by the opening springs 9a and 9b. With this rotation to the neutral position of 90 degrees, the open / close display pointer 90 also rotates by 90 degrees to indicate that it is open (neutral).

By this energization, the exciting coil 41b of the preliminary electromagnetic drive unit 4b is excited and the iron core 4b is attracted and moved into the exciting coil 41b. With the movement of the iron core 42b, the transmission rod 43b is swung to rotate the main shaft 3 via the drive plate 31, and the rotation of the main shaft 3 moves the movable contact 6 from the neutral position (open state) to 90 degrees. Only by rotating the auxiliary fixed contact 5b. With the rotation of the main shaft 3, the open / close display pointer 90 is further rotated by 90 degrees to indicate that the “preliminary power on” is being applied to the standby power supply.

Even when the main shaft 3 is rotated by manually rotating the a and 70b through the switching mechanism unit 700, the movable contact 6 is fixed to the regular contact or the spare fixed contact as in the case of the automatic switching. It can be brought into contact with any one of the children 5a and 5b to switch to the closed state, and at the same time, the open / close display pointer 90 can indicate which of the closed state and the open state. In this way, even if a power failure occurs on the utility power supply side, it is possible to immediately switch to the standby power supply side and supply power to the load side connected to the movable contact 6.

くなり円滑な切換動作ができないという課題を有する。Since the conventional switching switch is constructed as described above, it is possible to secure a sufficient opening contact distance when the switch is opened, but the main shaft 2 is left and right 90 degrees each. It has to be rotated at a large angle, and there is a problem that the link mechanism of the switching mechanism section 700 becomes complicated when the normal and spare operation handles 70a and 70b are manually operated for switching. In particular, when switching to the normal / spare power supply side and switching to the open state, the configuration of the link mechanism becomes more complicated. When the switching operation is performed by such a complicated link mechanism, there is a problem that the transmission loss increases and smooth switching operation cannot be performed.

The 0 also rotates 90 degrees, which increases the burden on the open / close display pointer 90 by being exposed to the wind and rain or the snow in the outside world, and also reduces the visibility when observing what is installed on the pillar from the ground. Have the problem of doing. The present invention has been made to solve the above problems, and proposes a switching switch that smoothly and reliably switches between two input modes for electric power with a simple mechanism and improves the visibility of the switching state.
